MAINTENANCE

Fuel Filter/Fuel Lines

See your POLARIS dealer for replacement of the fuel filter every 1000

miles (1600 km), or annually.

Inspect the fuel lines regularly for signs of deterioration or damage.

Always check fuel line condition after periods of storage. Normal

deterioration from weather and fuel compounds may occur. Replace

worn or damaged fuel lines promptly.

NOTICE: Kinking the fuel lines or using a pliers or similar tools to remove fuel

lines may cause damage to the lines. If a fuel line has been damaged

or kinked, replace it promptly.

Carburetor

The number stamped in the end of the main jet indicates the jet size. The

jet installed at the time of manufacture is not necessarily correct for your

elevation. Always ensure that the correct jets are installed in the

machine for the geographical area of operation.

NOTICE: Operating the snowmobile with incorrect jetting can result in serious

engine damage. Have your POLARIS dealer perform all carburetor

adjustments to ensure all adjustments are done correctly.

Carburetor Adjustments

The frequency at which the carburetors are synchronized or balanced is

important. Properly adjusted carburetors can greatly improve engine

performance, fuel economy, engine life, and reliability.

If you notice any of the following conditions, the carburetor may need

adjustment:

• Hard starting

• Poor idle

• Overheated pistons and cylinder walls

• Plug fouling

• Poor engine response to various throttle valve openings
